Timeout Error occurred When run a script on Headless chrome browser by using Selenium Webdriver with Python

Question

When I am running python scripts to test a website on Headless Chrome Broswer (Webdriver + Selenium), we often get a timeout error, I found out the problem occu

Answer 1

I faced same issue and was able to resolve it after updating my chromedriver and adding chrome_options.add_argument("--window-size=1920,1080") to the chrome options. The options I currently apply are:

chrome_options = Options()  
chrome_options.add_argument("--headless") 
chrome_options.add_argument("--window-size=1920,1080")
chrome_options.add_argument('--start-maximized')
chrome_options.add_argument('--disable-gpu')
chrome_options.add_argument('--no-sandbox')
chrome_options.add_argument("--disable-extensions")
chrome_options.add_argument('disable-infobars')

Answer 2

I was having a similar problem, normal Chrome driver worked fine, but headless chrome always timed out.

I found out that for responsive web pages, you need to set the window size:

driver.set_window_size(1200, 600)

It worked after adding this line just after initialization of the driver itself.

I hope this helps!
